l BOTTLE BEFRIGERATOB..

`Application iiled March 20, 1924. Serial No. 700,689.

To all whom z't may concern:

Be it known that I, ELIHU C. GRACE, a citizen of the United States,residing at Mobile, in the county of Mobile and State of Alabama, haveinvented `certain new and useful Improvements in Bottle Refrigerators;and I do hereby declare the following 'to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to bottle refrigerators, and has for its objectto improve the construction of the bottle holding tubes heretoforeproposed.

lVith these and other objects in view the invention consists in thenovel details of construction and combinations of parts more fullyhereinafter disclosed and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of thisspecification, in which like numerals designate like parts in all theviews:

Figure 8 is a fragmentary transverse sectional view similar to Figure 3illustrating the modification shown in Figure 7.

In order that the precise invention may be the more clearly understoodit is said In the Reissue Patent #15,d82, granted C tober 3l, 1922, toSoutullo, and ot which I am one .et the assignees ot record, there isdisclosed a refrigerator., provided with a plurality ot individualU-shaped tubes,

numbered ll and d5 in said patent, and

adapted to receive bottles as there disclosed. But in attempting tomanufacture these refrlgerators, it was discovered that the cost ofmaking these said tubeswas so excessive as to be commerciallyimpracticable. In fact, a little consideration will show that the onlypractical commercial way of mak- It was further found impracticableand'- too costly to make the tubes trom sectional pieces of metal asillustrated at 17 in said patent.

According to the present invention, on the other hand, I avoid theforegoing objec tions, and produce a commercial, practical, refrigeratorby providing the tubular structure now to be disclosed. Referring to thedrawings, l indicates an outer wall of a rerigerator box, and 2 an innerwall so' positioned as to form the air space 3 therebetween, serving toexclude heat and maintain the bor at a low temperature within, all inthe manner well known.,

4- represents the bottom ofthe box which may have attached thereto anysuitable supporting means 5. It desired an inner bottom 6 ot heatinsulating material may be provided, all as will be clear from Figures 2and 3,. Instead of providing the refrigerator with individual bottletubes, as in the reissue patent above mentioned, according to thisinvention, I provide an inner corrugated sheet ot metal il having itscorrugations running longitudinally thereof, and bend it into all-shaped torni, as indicated in Figures 3 and 6. 'lhe side edges ofthis lll-shaped sheet 11 are nent secured to end pieces 18, thus formingan inner tank adapted to form cooling chambers. Uutside this said inner.tank I provide a second and similarly corrugated sheet 10, which islikewise bent into a lll-shaped form, and ot such dimensions as willsnugly dt the interior of the refrigerator casing. That is to say, theoutwardly extending portions l2 ot the the tubes 15 to be formed.

corrugations in' sheet 10 'rest against the sides and bottom of therefrigerator as illustrated, while the inwardly extending portions 13 ofthe corrugations of the sheet 10 extend inwardly from said Walls orbottom of the refrigerator a distance approximately equal to one half ofthe diameter of The inwardly extending lportions 14 of the corrugationsin the sheet 11 are of such dimensions as to form the other half of thetubes 15 while the outwardly extending portions 16 of the corrugationsin the sheet 11 are of such dimensions that they substantially meet thecorrugated portions 13 in the sheet 10. The edges of the outer sheet 10are likewise closed by flat end pieces 17 similar to the members 18, andthus is an outer tank 30 formed into which fits the inner tank 31, aswill be clear from the drawin s.

The two tanks 30 and 31be1ng thus nested together, form a plurality oftubes 15 into which bottles 19 may be placed, as indicated. The endedges 20 of eachy sheet 10 and 11 may be crimped or otherwise attachedto the edges 21 of the end plates 17 and 18, as by the joints 22. suchas are best illustrated in Figure 4. Further, the upper horizontal edges'of the sheet 18 is provided with an extension 23 which is turned overto form the tubular portions 24 best shown in Figure 5, through whichpass the supporting rods 25 having the turned down ends 26 only'one ofwhich is shown in the drawings. The end sheets 17 have secured theretoas by the means 27 the angle supporting plates 28 on which the tubularextensions 24 rest and over the ends of which the turned down .portions26 of the rods 25 extend thereby positioning the inner tank 31.

32 and 33 represent any suitable refrigerating compartment and 34represents a cooling medium such as brine occupying the space betweenthe nested tanks 30 and 31, as Well as the bottle tubes 15, thus coolingthe bottles while partially supporting or buoying up the same` Thislatter action reduces friction `and renders it practicable to useabottle at one end of a. tube 15 to push out another bottle at the otherend of said tube.

That is, a construction of this kind forces or reminds the attendant toalways put a warm bottle into a tube 15 when he clesires to serve a coldbottle therefrom, and it insures the customer always getting the coldestbottle that is in the tube. The plurality of tubes enables theproprietor to keep on hand and to readily serve a great variety ofdifferent drinks.

The angle 28 and its coacting parts not only prevents the inner tankfrom shifting its position but renders it ossible to read ily remove theinner tank or cleaning and other purposes. lt is an important feature'sagewaya of this invention that the removal of the inner tank not onlyrenders the cleaning of the tubes 15 easy but it splits said tubes inhalves and thus enables the attendant to readily remove any brokenbottles, or an whole bottle that may from any cause stick in said tubes.Said angle bar 28 and rod 25 it will be seen also serve to position theinner tank 31 relative to the outer tank 30 in such manner to properlyform the tubes 15.

In Figures 7 and 8 is illustrated a modification of the constructionjust described wherein a lurality of tanks such as three is providedp toform a double row of bottle tubes. That is to say, there is provided anouter tank formed by a U shaped corrugated sheet 120 having plane endmembers 170. Within this outer tank is provided a second tank likewiseformed by a U shaped corrugated sheet 110 having plane end members 180and adapted to so fit within said outer tank that the corrugations ofthe one will form with the corrugations of the other a series of tubularpassageways through which bott-les may pass, all so far-as has beenheretofore disclosed.

A third tank likewise formed by a U shaped corrugated sheet 130 havingplane end members 190 and similar in all respects to the second tankexcept as to size, is disosed within said second tank in such a mannerthat the corrugations of the third tank will form with the corrufrationsof the second tank a series of tubular passageways adjacent theaforementioned series of pas- This third or innermost tank may besupported in and s aced from the second or intermediate tan in a mannersimilar to that employed in supporting and spacing the intermediatetank, or in any other suitable way, the particular method not beingillustrated in the accompanying figures.

It is obvious that those skilled in the art may vary the details ofconstruction as well as the arrangement of parts without departing fromthe spirit of the invention and therefore I do not wish to be iimited tothe above disclosure except as may be rcquired by the claims.
